Scientific Tuesdays – How to make paper invisible!!

In this episode of Scientific Tuesdays we will show you how to take a paper envelope and see directly through it, leaving no trace behind. We will explore how to take hexanes and put them to good use. Oh, science….

What's reading a letter going to do anyway?I mean, even if you read the letter, you're still going to give it to your parents at the end of the day so what's the point?
